Report Abuse. The collision of an oceanic plate, and a continental plate produce a plate boundary known as a subduction zone. The colder, denser [typically basaltic crust (approx. 3.3g/cm^3)] oceanic plate is forced underneath the less dense [typically granitic (d= 2.7)] continental crust.
Oceanic plates are typically heavier, and more dense, than continental plates, so when they collide the oceanic plate is forced down under the edge of the continental plate creating a subduction zone. Subduction zones create two significant geologic formations, magma chambers and fault lines.
